Data set contains air temperature data for coastal reserve LTER site Randu meadows, Latvia, 1996-2012

insect (Diptera, Chloropidae) data of grasslands of coastal reserve Randu Meadows. Latvia. Insects were collected on 5 transects (26 m) along coast line perpendicular to the coast.From 1996-2012 three times per year monthly (June, July, August) insects were collected by entomological sweep net method along each transect (50 sweeps). Seasonal data were obtained by pooling monthly data for each transect.

Botanical reserve “Randu meadows” is situated on the northern coast of the Riga Gulf. The botanical reserve is a part of the North Vidzeme Biosphere Reserve. It represents about 200 ha of unique coastal meadows with high habitat and species diversity. There were recorded 531 plant species, 42 are rare and protected in Latvia, 2 species are on the EU Biotope Directive 92/43/EEC list. Man has participated in the development of these littoral meadows for hundreds of years, by cattle grazing and hay harvesting. Recently, the intensity of grazing and mowing have sharply decreased, and the meadows are gradually overgrowing by reeds and shrubs. Wild cattle herd was introduced for some time in part of the grassland area in order to prevent overgrowth of meadows.
